我省红壤面积很大,可垦荒地约有1,500万亩,绝大部分丘陵起伏,坡度达5—10°(8.75—17.5%),有机质缺乏,土质结构不良,胶质性状差。加之我省春夏两季雨水充沛,据历年记载,3—6月降雨占全年58.2%,且多是雷阵雨和风暴雨出现,降雨强度每小时高达57.1毫米(10分钟降雨强度为20.8毫米),日降雨有达170毫米的约占全年1/10。同时,由于森林破坏及群众过度铲草皮的结果,引
The area of red soil in our province is very large. About 15 million mu can be reclaimed and cultivated. The vast majority of hilly areas have a gradient of 5-10 ° (8.75-17.5%), lack of organic matter, poor soil structure and poor glial properties. In addition, the spring and summer rainfall in our province is plentiful. According to the historical records, from March to June, rainfall accounted for 58.2% of the whole year, mostly due to thunderstorms and rainstorms. The rainfall intensity reached 57.1 mm per hour (rainfall intensity of 20.8 mm in 10 minutes) The daily rainfall of 170 mm accounts for about 1/10 of the whole year. At the same time, due to the destruction of forests and the result of over-shoveling and scrapping by the masses,
